Tooth 27 Decay: Symptoms, Causes, and Prevention

The Location Tooth 27: Understanding the Lower Left Canine

Tooth 27 is the mandibular right canine, as per the universal numbering system for teeth. Present in the lower right quadrant. The details of all four quadrants are available on our website.

Tooth 27 Location

Tooth number 27 is located in between tooth number 28, which is the premolar or first bicuspid in the lower left quadrant, and tooth number 26, which is the lateral incisor in the lower left quadrant. Check out the anatomy of tooth 27 here.

Tooth number seven is one of the four canine teeth. The canine tooth number, regardless of number or quadrant, is called the cuspid, eye tooth, or fang. However, since they are easy for dentists and orthodonticians to identify by their numbers.

Is the 27th Tooth Also Anterior or Posterior?

Yes, not only tooth 27 but all other canines and incisors are also anterior. No matter if it is maxillary canines or incisors or mandibular canines or incisors. Anterior represents the front region of the mouth, which includes canines and incisors from both the upper and lower jaws.

Posterior represents the back region of the mouth, which includes the premolar and molar for both the upper and lower jaws.

The value of tooth number 27 serves to show how different teeth in the mouth work together and depend on each other.

FDI and Plamer Number for Tooth Number 27

FDI is also universally followed as a tooth numbering system. 

  • Tooth number 27 is given number 3 in the Palmer numbering system in the lower left quadrant.
  • While in FDI, it is given the number 43 in the lower left quadrant for tooth number 27

The Sharpness of Tooth Number 27

Tooth canine 27 and the other canine teeth (human) are sharp and pointy, fang-like, but they have nothing to do with vampires. They are pointy because their sole purpose is to tear and bite the food and also to balance the jaws when closing the mouth, as they are the longest teeth in the mouth.

Some people even have rounded and less sharp canines than others, and that is totally a cultural and environmental thing.

Reshaping the Tooth Number 27

Reshaping mandibular canine tooth number 27 involves a procedure called dental contouring. Which is also called odontoplasty or enameloplasty. Generally, the process includes the following:

  • It is the dentist who is going to decide if you need a reshaping or not. The dentist will check your canine teeth, along with the structure and alignment of all the teeth in the mouth, and then decide whether to go for a procedure or not.
  • During the contouring process, the dentist uses a special, specific tool to remove the same amount of enamel from tooth canine 27 and other canine teeth. This removal helps reshape the canine teeth for alignment or facial aesthetic purposes. 
  • After the tooth has been reshaped, it will be smoothed and polished to make it look normal and good-looking. This makes the tooth look more like the other teeth around it.

Follow-ups after the procedure are a must to ensure the tooth is going well. If you are going for this contouring procedure, choose a professional dental surgeon. Look for an expert to make sure that the procedure is safe and has effective results

Contouring Side Effects and Recovery

While contouring makes your teeth look more reasonable, it has its side effects too. The removal of enamel can cause various problems for the canine teeth, which include:

  • Tooth Sensitivity
  • Increased chance of tooth decay
  • Yellow teeth

But if you are worried about the recovery of tooth 27 or other canine teeth after dental contouring, there is no need for you to worry. The teeth can get back to their normal functionality after contouring; there is no need for some special treatment for recovery. The only thing that you should take care of is your sensitivity to cold and heat. Too much hot or cold food can make your teeth suffer, so avoid such foods for a few days.

Decay of Tooth Number 27

It is important to note that if given proper oral hygiene, the canine teeth will stay with you for a long time. And if not taken care of, canine teeth can also develop decay. Decay of the canine teeth, including tooth number 27, can start with the plague that sticks to the teeth. A sticky film of bacteria that attacks the enamel of the canine teeth or other teeth.

To avoid bacteria on your teeth, avoid acidic and sugary foods and carbohydrates (drinks). You should always use fluoride toothpaste. Take good care of your teeth by brushing them twice a day and flossing them once a day.

Tooth Number 27 Extraction

27th Tooth, canine extraction removes the mandibular left canine, popularly known as the “eye tooth.” When a tooth is significantly broken, decaying, diseased, or creating oral health issues, extraction is suggested.

Tooth 27 extraction involves a surgical procedure to removes the lower left canine tooth from its jawbone socket. Dental professionals may use local anaesthetic or sedation to keep patients comfortable. The possible reason for extrcation are:

  • Tooth number 27 decay that cannot be repaired with dental fillings or root canal therapy, extraction may be essential to avoid infection and protect neighbouring teeth.
  • Advanced periodontal (gum) disease can destroy the tissues and supporting structures around 27th tooth, making it unstable. To prevent gum and bone damage, extraction may be necessary.
  • 27th tooth, canine may need to be extracted if it fails to erupt or is misaligned with the surrounding teeth. Impacted canines can crowd, misalign, and harm neighbouring teeth.
  • If 27th tooth, canine is badly shattered or traumatized, extraction may be

Tooth Number 27 Anatomy

Here is a brief description of the anatomy of tooth 27:

  • The crown of tooth 27 is the visible part above the gum line. It has a distinct shape resembling a pointed cusp.
  • The root of tooth 27 is located below the gum line and anchors the tooth into the jawbone.
  • Enamel is the outermost layer of the tooth’s crown.
  • Dentin is the layer beneath the enamel and makes up the majority of the tooth’s structure.
  • Pulp is the innermost part of the tooth, located in the pulp chamber and root canals.
  • Cementum is a layer of hard tissue that covers the root of the tooth.
  • Periodontal Ligaments connect the tooth root to the surrounding bone, providing support.

Tooth number 27 has the single root. The root canal is a hollow space within the root containing pulp. The tooth number 27 oot canal is slighltly S shaped. The 27th tooth root canal treatment helps in disinfecting the pulp infection and to seal them to avoid any furthur infection attacks.

If root canal treatment is not done on time, it can cause the infection growth and at the end people have to go for tooth extraction.
